This article provides an overview of the corrosion theory relating to refractories on the basis of acid/base reactions, thermodynamics, and kinetic considerations. The tests to evaluate refractory corrosive wear are reviewed. The article describes the specific refractories used in steel, glass, aluminum, and chemical-resistant applications. Specific material issues that should be considered or evaluated when choosing or using refractory materials are discussed.

This article provides a discussion on the structural ceramics used in gas turbine components, the automotive and aerospace industries, or as heat exchangers in various segments of the chemical and power generation industries. It covers the fundamental aspects of chemical corrosion and describes the corrosion resistance characteristics of specific classes of refractories and structural ceramics. The article also examines the prevention strategies that minimize corrosion failures of both classes of materials.

All refractory metals, except osmium and iridium, have the highest melting temperatures and lowest vapor pressures of all metals. This article discusses the commercial applications, and production procedures of refractory metals and alloys. These procedures include fabrication, machining, forming, cleaning, joining, and coatings. The article also presents information on, and specifications for, the following metals and their alloys: niobium, tantalum, molybdenum, tungsten, rhenium, and refractory metal fiber-reinforced composites. It discusses the processes involved in their production, their mechanical properties, physical properties, thermal properties, electrical properties, chemical properties, applications, and corrosion resistance.
